His body was found at a holiday flat in Brighton on July 14 and officials say the cause of his death is still not known.

A 60-year-old-man has been arrested and bailed in connection with the death.

Sussex Police investigating the incident last night said they believe they know the identity of the man, although they have yet to officially name him.

It is thought the two men knew each other.

Mr Whyte’s body was found by neighbours in a dwelling at Chesham Place, Kemp Town, at 3.30am on Tuesday of last week.

The property had been rented from July 9 and the occupants had been due to check out that morning. A spokesman for Sussex Police said: “A 60-year-old man who was arrested on suspicion of murder in connection with the death of a man in Brighton has been released on bail until September 30.”

They also confirmed that a post-mortem had been carried out but said the results were “inconclusive”.

“Further toxicology tests will now be carried out,” the statement went on.

“Although officers are confident they know the identity of the 54-year-old man, he has not yet been formally identified.”

No reason has been provided for the delay in the man being officially named.

After the body was found, a communal bin was searched and sealed by police.

Forensic officers could be seen carrying bags of evidence from the flats complex in the popular seaside resort.
